SPECIFICATION forming part of Letters Patent No. 777,133, dated December 13, 1904.

Application filed .1,; t

To all whom/ (it may concern.-

Be it known that I, NELS OLSSON, a citizen of the United States, residing at La Crosse, in the county of La Crosse and State of 1V isconsin, have invented certain new and useful improvements in Pipe-Organ Attachments; and I dohereby declare the following to be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make and use the same.

My invention relates to musical instruments, and more particularly to the construction involved in producing the action or controlling mechanism for the valves of a pipe-organ, whereby a minimum amount of force is required to operate said parts; and my invention consists of certain novel features of construction and combination of parts, the preferred form whereof will be hereinafter clearly set forth, and pointed out in the claim.

The prime object of my invention, among others, is to attain great ease of action or operation of the parts.

A further object of my invention is to simplify the construction to a minimum degree, n hereby the parts may be cheaply and expeditiousl y manufactured and each readily assembled in its respective operative position.

Other objects and advantages will be hereinafter made clearly apparent, reference being hadto the accompanyingdrawings, which are made a part of this application, and in which Figure 1 shows a side elevation of my pipeorgan action complete ready for use. Fig. 2 is a vertical sectional view thereof. Fig. 3 is a sectional view of Fig. 1 on line 3 3 thereof. Fig. 4 is a sectional view of Fig. 1 on line 4 4. is a perspective detail view of parts of my improved action for pipe-organs, fee, while Fig. 6 is a similar view showing means for adjusting the fulcrum-point.

The various parts of my invention and cooperating accessories willfor convenience be designated by numerals, the same numeral applying to a similar part throughout the several views.

Referring to the numerals on the drawings, 1 designates the base portion or support of the usual or any preferred construction, while Serial No. 219,093. (No model.)

2 and 3 designate the keys of the pipe-organ arranged in the usual manner to provide a complete keyboard for the instrument. The key 2 is properly fulcrumed by means of the post 4. carried by the framework 1 in any preferred ay and passing up loosely through an opening 5 in the key. Near the inner end of the key 2 ll secure the pin or linger 6, which is rigidly placed in position and is adapted to pass up loosely through a slotted opening 7 in the transmitting-lever 8, which latter is provided with an opening on its inner end to loosely fit over the pin 9, carried by the cross-bar 10 or the equivalent thereof.

The transmitting-lever 8 is provided with the adjustable fulcrum-point 11, having a stem 12, which passes loosely through the slotted opening 7 in the transmitting-lever 8, said stem 12 being retained in place in any preferred way, as by a nut 13 or equivalent device.

The controlling-lever 14 is pivotally secured near its middle portion, as designated by the numeral 15, to the upright or post 16, constituting part of the framework. The outer end of the controlling-lever 14 is pivotally connected to the transmittinglever 8 by means of the postlT, while the opposite end of said controlling-lever is operatively connected to the valve 18 by the intermediate link-sections 19 and 20, whereby pivotal union between the controlling-lever and valve is secured.

The valve 18 is held normally upward by a suitable spring 21, secured in place as by passing the end thereof into the bar 22, while the other end is entered in an aperture in the valve. It will be understood that the said valve is in communication with the air duct or chamber 23. and when said valve is drawn downward by the operation of the key 2 the air under pressure is admitted through any of the instruments or pipes 24, as common, thereby insuring that volume of sound will be produced. l. have also provided and properly connected the key with a valve 25, also located in an air duct or chamber 26, as is common, whereby any of the tubes or pipes 27 communicating therewith will be placed in operation.

The key 3, it will be observed, is provided with an aperture 23 to loosely fit over the finger 29, carried by the cross-bar 30, while the inner end of the key is also provided with the finger 31, which extends upward through the opening 32 in the outer end of the bar 33, the inner end of said bar being pivotally connected to the supporting member 34, constituting part of the framework, said supporting member 34 having the finger 35 passing loosely through an aperture in the inner end of said bar 33 or a continuation 36 thereof when said bar is formed in two separate sections. The bar 33 is also provided with the finger 37, placed in pivotal connection with the bellcrank 38, which latter is properly mounted in a bracket 39, carried by a portion of the framework. The bell-crank 38 is operatively connected with the bell-crank 4L0 by the link #11, and it will be observed that the valve 25 is placed under the control of the bell-crank 40 by means of the link 41 or equivalent device, said valve 25 being held normally closed by a suitable spring 42, corresponding to the spring-21.

By means of the construction just described it will be observed that either one of the valves 18 or 25 may be opened, as desired, by a simple pressure upon the key 2 or 3, as the case may be. It will be observed that the bar 33 is provided with an adjustable fulcrum-point L3, having a stem 4% located in the slotted opening 32 and secured therein by the nut 45 or other equivalent means. It is obvious that by moving the fulcrum-points 11 or 43 outward toward the ends of their respective levers or bars that a different result will be at tained than when said fulcrumpoint is moved inwardthat is to say, for instance, when the fulcrum-point 11 is moved outward in the slot 7 said fulcrum-point will be disposed nearer the fulcrum-point of the key 2, and the valve will require much less force to operate it than when the fulcrum-point 11 is moved inward to the full extent of the slotted opening 7,

l l L l thus enabling the desired tension for each key to be readily attained, such tension being secured by means of a proper adjustment of the fulcrum-point. It follows, therefore, that any desired touch for the keys may be readily secured by proper adjustment of the fulcrumpoints 11- and 43, as will be obvious from the foregoing description considered in connection with the accompanying drawings.

Believing that the advantages and manner of using my invention have thus been made clearly apparent, further description is deemed unnecessary, and while I have described the preferred combination and construction of parts I desire to comprehend in this application all such substantial equivalents and substitutes as may be considered as falling fairly within the scope and purview of my invention.

Having thus fully described my invention, what 1 claim as new, and desire to secure by Letters Patent, is

The herein-described controlling action for pipe-organs and the like comprising the combination with the keys of the instrument and valves controlling each individual pipe, of a system of levers consisting of the transmit ting-bar 8 pivotally secured at its inner end and having an adjustable fulcrum-point at its outer end adapted to bear upon the end of said key; a controllinglever 14 pivotally mounted in position and operatively connected with said valve and said transmitting-bar whereby a downward pressure upon the key will open said valve and suitable means to adjust the fulcrum-point carried by the transmitting-bar, all combined substantially as specified and for the purpose set forth.

In testimony whereof I have signed my name to this specification in the presence of two sub scribing witnesses.

NELS OLSSON.
